Patent EP-0306947-A3 (EP)
Title: Image recording ink
IPC: B41M5/26
Filed: 1988-09-08
Abstract: An ink which can cause a change in its 
adhesiveness by an electrochemical reaction is obtained 
by impregnating a crosslinked substance such as 
polyvinyl alcohol with a liquid dispersion medium 
comprising an organic solvent having a relative 
dielectric constant of 15 or larger at 25 °C such as 
ethylene glycol. The ink shows little characteristic 
change due to drying, etc., and suitably retains its 
fluidity when left standing in the air for a long 
period. The ink is supplied with a pattern of energy 
to be provided with an adhesive pattern, which is then 
transferred to a recording medium such as plain paper, 
directly or by the medium of an intermediate transfer 
medium to form an ink pattern corresponding to the 
energy pattern applied.
Patent EP-0303341-A3 (EP)
Title: Output buffer circuits
IPC: H03K19/003
Filed: 1988-06-15
Abstract: An output buffer includes a pull-up transistor (N1), a first pull-down transistor (N3), a second pull-down transistor (N8), and a logic circuit (15). The logic circuit (15) is responsive to a data input signal making a high-to-low transition and the output signal making a high-to-low transition for maintaining the second pull-down transistor (N8) turned-off until after an output node has made the high-to-low transition, thereby reducing significantly the ground bounce noise.

Title: Inlet manifold and methods for increasing gas dissociation and for pecvd of dielectric films
IPC: C23C16/30
Filed: 1988-08-12
Abstract: An inlet gas manifold (11) for a vacuum deposition chamber (10) incorporates inlet apertures (31) which increase in diameter or cross-section transverse to the direction of gas flow (22). The aperture configuration increases the dissociation gases such as nitrogen and, thus increases the rate of silicon nitride deposition provided by nitrogen gas chemistry, without requiring the use of reactants such as ammonia. While one could use ammonia in the deposition gas chemistry if desired, the process provides the option of completely eliminating ammonia The inlet manifold (11) containing the increasing-diameter gas inlet holes (31) provides enhanced control of the process and the deposited film, and is also useful for forming other dielectrics such as silicon oxide and silicon oxynitride. In particular, silicon oxynitride films are characterized by low hydrogen content and by compositional uniformity.
Patent EP-0306234-A3 (EP)
Title: A flip-flop arrangement
IPC: H03K3/037
Filed: 1988-08-26
Abstract: A delay type flip-flop arrangement using transistor-­
transistor logic receives a clock signal (CP) and input 
data (D) and outputs a logical output (Q) in accordance 
with the logic level of the data. The arrangement 
includes a master flip-flop (1) for transmitting a change 
in the logic level of the data to a pair of output ends 
(N1,  N1 ) when the clock signal is at a predetermined 
logic level; a slave flip-flop (2) for latching the data 
transmitted via the pair of output ends; an output buffer 
(3) for effecting a buffering of the data latched in the 
slave flip-flop; and a drive circuit (4) for driving the 
output buffer. The drive circuit responds to logic 
levels of data (Q1,  Q1 ) appearing at the pair of output 
ends of the master flip-flop and, based on the logic 
levels, drives the output buffer to determine the logic 
output (Q) to be output from the arrangement. This 
reduces the total propagation delay time and realises a 
high speed operation without increasing the power 
dissipation.

variety of recombinant DNA vectors. The vectors are 
useful in producing IPNS in a wide variety of host 
cells, such as  Streptomyces ,  Penicillium , and 
 Cephalosporium . DNA compounds encoding the tran­
scription and translation activating sequence and 
transcription termination sequence of the IPNS gene are

Title: Variable gain analog-to-digital conversion apparatus and method
IPC: H03M1/10
Filed: 1988-12-16
Abstract: A variable gain analog to digital compression 
encoder apparatus and method is operational for 'on the fly' 
gain adjustments without introducing significant distortion 
or noise in telephone conversation. An incoming analog 
signal (9) is fixed gain (11) reproduced as a first 
stabilized mid-operating point analog signal (41). A second 
stabilized mid-operating point analog signal (42) is produced 
in inverse proportion to the first stabilized mid-operating 
point analog signal, in response to a signal (43) tapped 
along a signal division of a difference between the first and 
second signals. The second signal is compression encoded 
(13) at a predetermined rate to produce pulse code modulated 
signal samples (25). The tap may be varied (44) to change 
the encoding gain, at any time, in accordance with operating 
requirements of a telephone apparatus.

of restraining, or not, the displacement of a suita­
ble shaped lug extending from the inner face of the 
block and driven by a lever arm in turn driven by a 
handle.

Title: Data reproducing system
IPC: G11B11/08
Filed: 1989-06-05
Abstract: When current is caused to pass between a data 
carrier (20) and a stylus (23) while causing the latter to approach

the distance between the two is reduced to a certain 
extent.  
     According to the invention, the data carrier and 
stylus are made of a conductive material, and a closed 
circuit for passing current therethrough is formed 
between the data carrier and stylus. Raised or recessed 
portions (22) formed on the surface of the data carrier can 
be read out to reproduce data by detecting the tunnel 
current flowing through the closed circuit.

Patent EP-0371561-A3 (EP)
IPC: G11B5/725
Filed: 1989-11-27
Abstract: System comprising a magnetic head (1) and a magnetic 
information carrier (2), which cooperate with each other through a 
layer (3) wiih soft magnetic and lubricating properties. The layer (3) 
is anisotropic, the relative permeability (µx) of the layer, taken in a 
direction parallel to the head face (2), being less than the relative 
permeability (µy) of the layer in a direction perpendicular to the head 
face (9). By using the said layer in systems in which a certain 
distance between the magnetic head (1) and the information carrier (2) 
is desirable, the magnetic resistance is reduced and the signal-to-­
noise ratio is improved. The layer (3) may be present on both the 
magnetic head (1) and on the information carrier (2) as well as on both 
of them.

Title: Container bag
IPC: B65D88/16
Filed: 1989-05-10
Abstract: A method of making an intermediate bulk container having zones (12) for the attachment of lifting loops (20) from a fabric (10) having eight such zones with lifting loops attached to the zones comprises attaching the opposite selvedges (14, 16) of the fabric together and then attaching the base (26) to complete the bag. The zones (12) are arranged in four pairs with a zone (12a) of one of the pairs being adjacent to one of the fabric selvedges (14). The side seam (24) of the bag so made is thus spaced from its adjacent corner. This means that all four lifting loops can be attached to the fabric while it is still in the flat state since no lifting loop has to cross the seam in the finished IBC> This form of construction lends itself to automatic stitching processes and radically increases speed of production.

Title: Controlling dynamic tracking heads of digital video tape recorders
IPC: H04N5/783
Filed: 1989-07-21
Abstract: A dynamic tracking head (HA, HB) of a digital video tape recorder 
is controlled so as to reproduce a digital video signal of which one 
field video signal is recorded on a plurality of segmented video tracks

drum increased for the heads (HA, HB) to trace precisely the 
plurality of video tracks forming one field video signal (e.g.  i ) in a 
shorter time, thereby to obtain a sufficient time for the video heads 
(HA, HB) to jump from the end portion of the video tracks to the 
beginning portion of the next video tracks.
